In an interview, Paul McCartney described his visit to Los Angeles, California, to see John Lennon during the singer's "Lost Weekend" in 1974. "So I went out there and he was doing Pussy Cats with Nilsson and Keith Moon and Jesse Ed Davis, to name just three total nutters. Three beautiful total alcohol nutters plus John, forget it! Even the location is perfect. We went 'round to a session and sat there for a bit. It was a little bit strange, John and I, seeing each other at that time. But then we dropped by their house the next day for a cup of tea or something. I remember Harry Nilsson offering me some angel dust. I said 'What is it?' He said, 'It's elephant tranquillizer.' I said, 'Is it fun?' He thought about it for about half a minute. 'No,' he said. I said, 'Well, you know what, I won't have any.' He seemed to understand. But that's how it was there."[1]

 

Harry Nilsson visited the Beatles in London while they were recording their "White Album." One evening, Paul McCartney visited Harry and his wife, Diane, in their hotel room. Paul had brought along a guitar and treated the couple to an acoustic sample of the songs the group was recording for the album.[2]
